Large Ground Fissure Found Near Unit 1 Fukushima Daiichi researcher Elaine Kirk found this image that was posted on the TEPCO website on June 14th of Unit #1 at Fukushima Daiichi. It shows a very large and deep fissure that runs right up to the reactor building. It is unclear what date the image was actually taken on. The odd quality of the image is due to it being some sort of laser survey of the power plant.

There are concerns that this large fissure could have also had some impact on the integrity of the lower levels in unit 1.

    If you look at the tree down right and the pole just below the fissure, and look at the shadows they cast, and you can see the angle of the light and length of the shadow. When you then look at the fissure, you can see that it subsided on the left, and even roughly how much it subsided all along the fissure.

    I’ve had a look through most of the tepco documents that are not standard release radiation measurements, I cannot locate this image in the quality you have available. We are conducting research into ground faults and methane hydrates in relation to corium.
    Can you please post your source exactly.
